The split is 65% liquor, 15% beer and 20% wine: what a former country-club banquet captain sees at weddings. A beer crowd, a wine dinner, a champagne toast or a different guest count? Run your own numbers in the alcohol calculator.
Bartenders
4 bartenders if all 100 guests hit the bar at once, as after a ceremony. 2 if arrivals spread out. A beer-and-wine bar pours faster and needs fewer: see the staffing calculator.
How the math works
2 drinks per guest in the first hour, then 1 per guest per hour. A 750 ml bottle of wine pours 5 glasses of 5 oz; a 750 ml bottle of liquor pours 16 shots of 1.5 oz (NIAAA standard drinks). Beer is one can or bottle per drink. Mixers are about 4 oz per mixed drink, and ice is 1 lb per guest for drinks, more if you chill bottles in tubs. Count only guests of legal drinking age who drink.
